But Go's power really is it still minimalistic approach that keeps it easy to read, follow and function. Implementations will be completed in the remaining layers. Loose coupling: The parts of the system will interact with each other through the definitions and principles laid down in the Core layer (interfaces, abstract classes, base classes, etc.).

Quite opposite really and really enjoy practicing and applying CQRS principals at scale. Advantages and disadvantages of Domain-Driven Design Advantages of DDD. :Scott Millett and Nick Tune :Patterns, Principles and Practices of Domain-Driven Design : WROX : 2015 : PDF : 27. Advantages and disadvantages of Domain-Driven Design Advantages of DDD. Evans' book, there is Domain Driven Design Quickly that I usually buy copies for for friends:Įdit: I am not a DDD hater. PS, to save you from falling asleep reading Mr. If you flood it with 50 domain objects, 19 aggregates, 40 value objects, 70 specifications, and 5 modules - it is no longer easy to follow.ĭDD, while needed in OOO languages, tends to have an adverse effect in Go where things end up being more complicated with object graphs of several structs and aggregates - when you could have just wrote a single func that took parameters and returned an error. The best packages are those that the API is self explanatory. It describes independent problem areas as Bounded Contexts (each Bounded Context correlates to a microservice), and emphasizes a common language to talk about these problems. In the context of building applications, DDD talks about problems as domains. Keep a close eye on your exported API to make sure it makes sense to others. Domain-driven design (DDD) advocates modeling based on the reality of business as relevant to your use cases. Just do the minimal and keep things decoupled in your same package for easier testing.

Struct alignment for CPU cache optimizations, lower memory graphs, stack vs heap, etc.Īfter a solid 3 years in Go, there's very little DDD I use these days as I found the code I wrote less efficient and harder for other people to read.

One concept is that the structure and language of software code (class names, class methods, class variables) should match the business domain. and that is where I wasted months of time and effort.Īfter reading what seems like 100s of articles and golang group messages from the developers of Go, I came to realize I was doing it all wrong. Domain-driven design (DDD) is a software design approach focusing on modelling software to match a domain according to input from that domain's experts. NET for 12 years, where I practiced DDD, BDD, TDD and most recently CQRS and MicroServices for many many years, when I switched to Go in 2014 I immediately went down the path of DDD and CQRS with strong OOO.
